INTERNAL-COMBUSTION Ell'GlNE.

Specification of Letters Patent.

Patent ed June 28 1915.

Application filed June 29.1914. Serial No. 847,870.

To all whom it may concern Be it known that I, Hrnnox ll. LAYn-m, a citizen of the United States. and residing at New York. in the county of New York and State oi. New York, have invented certain new and useful Improvements in Internal- (ombustion llngines, of which the following is a specification, such as will enablethose skilled in the art to which it appertains to make and use the same.

This invention relates to explosion or internal combustion engines and particularly to engines of this class of the sleeve valve separate parts of my improvement are desis nated by suitable reference characters in each of the views, and in which 1- Figure 1 is a central ertical section of the top portion of the cylinder of an explosion engine made according to my invention together with the explosion head of the cylinder and the inlet and exhaust manifolds. Fig. a View similar to Fig.1 but showing a modification; and, Fig. 3 a View similar to l ies. 1 and 2 but showing" another modification. v

in the drawing forming part of this specification, l have shown at a the'ton portion of the cylinder oi an explosion ene'ine containing the usual piston 7). and at c I have shown the explosion head of the cylinder wh ch is formed separatel and. inscrt-ihle from the bottom of said cylinder. The cylinder 1 is provided with an extension 0 which forms an inclosingr casinq or jacket 'For the explosion head and in the construction shown. the said extension 0, is reduced in size and the top portion of the explosion head and said casing or jacket are both of less transverse dimensions than the c linder, thus producin; a contracted and inwardly inclined shoulder at the top of the cylinder. and the brttoin of the explosion head a is providedwith an annular enlargement c which abuts against the shoulder a when the head is inserted from the bottom of the cylinder. 1 have also shown at (Z and c the inlet and exhaust manifolds of the engine, andsaid manifolds are provided with inlet and ex" haust ports or passages (Z and 0 controlled by a sleeve valve fmovable in a sleeve ralye chamber ,7 formed between the top cylindrical portion c of the explosion head 6 and the extension a of the cylinder. The cylin- 'der a is also inclosed by the usual casing or jacket a, which unites with the extension (1 of the cylinder just below the inlet and exhaust manifolds (Z and c, as shown at a, and in the construction shown the parts (I, 0?, (E and d and c are all formed integrally but this is not absolutely necessary. The extension a of the cylinder, or the casing or jacket formed by said extension and the explosion head 0 are provided with a detachahlecap It, and while I have shown but. one cylinder it will be understood that the engine, in practice. is made up of a number of such cylinders and the cap it applies to all of them.

The explosion head a of the cylinder is provided with an explosion chamber (1", the lower end portion of which communicates with the cylinder and is funnel-shaped in form as shown at c, and the top portion of which is provided with a transverse partition 0 having a threaded bore or passage 0 in which the sparking: plug is secured said sparking plus being not shown. The explosion head 0 is also provided with an annular Water chamber or passage c which inc'loses the explosion chamber and the lower end portion of which is enlarged as shown at 0 to correspond with the annular enlarg; ments 0 at the bottom of the explosion head and. in the construction shown. the bottom and top walls of the annular enlargement 0 of the water chamber or assage 0 are rein forced or braced at 0 The detachable cap 7a is also put in communication with the water chamber or passage a by means of ports or nassanes I1 and the inclosin; casiufr or jacket of of the cylinder forms a water chamber or passae'e i which incloscs the eviinder and the bottom part. of the explosion head and is placed in communication with the annular enlargemrmt 1: of the water chamber or passage ('1 by ports or passages 5 and in the use oi the outline the water from the radiator enters the bottom portion of the chamber or passage i in the usual manner and passes upwardly around the cylinder and into the bottom portion of the explosion head and up through the chamber or passage and into the detachable cap It will be readily understood and the valve is inserted before the cap it is applied, andby means of this method of forming, finishing and assembling said parts, the expense of forming and finishing the valvechamber is largely reduced. and the assembling of the parts facilitated, as will be readily understood. The explosion chamber 0 of theexplosion head is provided with an upwardly directed extension o on which is screwed a nut ,7 which bears on the cap h and aids in drawing the explosion head into position and securing it therein.

In the construction shown in Fig. 1, the vertical or longitudinal dimensions of the explosion chamber 0" are much greater than 301the transverse dimensions, and the valve chamber, or the casing thereof, is water-,

jacketed only on the inner side thereof, this result being obtained by reason of the fact that the water chamber or passage 0 is iformed in the explosion head of the engine,

' but in Fig. 2 I have shown a modification in which the explosion chamber 0 is shortened and enlarged transversely, and in this form of construction the water casing or jacketa 40 .which incloses the cylinder at is extended upwardly and incloses the inlet and exhaust manifolds d and e and the valve chamber 9,

or the annular casing forming the valve chamber is Water-jacketed on the outer side 5 only instead of on the inner side as shown in Fig. 1, the upward extension a of the casing or jacket (1 which incloses the inlet and exhaust manifolds forming a supplemental Water chamber or passage i which is in communication with the chamber or passage i, as shown at i, and the water chamber or passage '5 is in communication with the cap it as shown at i", and the cap it is also enlarged transversely,.and with these exceptions the construction shown in Fig. 2

is the same as that shown in Fig. 1.

In Fig. 3, I have shown another modification in which the valve chamber r or the casing thcrcof, is water-jacketed both on the inner and outer sides thereof, the explosion head (1" being provided inwardly of said alvc dhamhcr. or the casing thereof. with the water rhan'ibcr or passage r as shown in Fig. 1, and also with. the water chamber or passage 2' as shown in Fig. 2. In this town of construction, the water chamber or sage ,2' is placed in communication with the bottom of the explosion head or the water chamber or passage 0 therein, as shown at '6 and the water flows up throne h the chamber or passage 2' into the chamber or passage 2' and into' the bottom of the chamber or passage 0 and from the chamber or passage 0 and the chamber or passage z, the water flows into the cap It in the same manner as in Figs. 1 and '12, and with this form of construdtion, the. valve f,

or the casing thereof, is water-jacketed on both sides and there is a complete flow of water in a continuous direction on both so sides of said valve or valve casing, as indi cated by the arrows m, and arrows it also indicate the flow of the water in Figs. 1 and 2.

In all the forms of construction shown to the explosion head as well as the valve and. valve chamber are of less transverse dimensions than the cylinder, but my invention is not limited to this construction, all that is necessary, in this respect being, that the dimensions of said parts be such as to permit the insertion of the explosion head from the bottom of the cylinder and the proper fitting of said explosion head in the, top of the cylinder. or the extension thereof. 9

Having fully described my invention, what I claim as new and desire to secure by Letters Patent, is 2-.

1. In an explosion engine, a cylinder provided with an extension above the working portion thereof, an explosion head which is inserted into said extension from the bottom of the cylinder, the extension of the cylinder and said explosion head forming an annular valve chamber above the 'worl'z 1 .ing portion of the cylinder, and a sleeve valve placed in said chamber and above working portion of the cylinder and hide pendent thereof.

4. In an explosion engine, a cylinder provided with a reduced extension at the bottom of which is an annular shoulder, an explosion head containing an explosion chamber and insertihle from the bottom of the cylinder and between which and said extension is a valve chamber, said explosion gig head being provided at its lower end ivith an annular enlargement which abuts against said shoulder.-
